The Tesla Model S — Consumer Reports’ test car has some glitches.

When Consumer Reports tested the all-electric Tesla Model S in the summer of 2013, the magazine raved. The car achieved the editors’ top test score, no mean feat in the Consumer Reports world of rigid testing and high standards.

Earlier this week, however, the magazine said its test car has developed a number of minor faults — retracting door handles not opening, thereby preventing entry to the car; the big center screen, which has many of the car’s functions, going blank; the front trunk lid’s opener going inoperative; and the editors “also had the adapter for the non-Tesla EV charger come apart.”

For a luxury sedan whose price ranges from nearly $70,000 to about $94,000, these electronic gremlins could tarnish the car’s reputation. The magazine’s editors stressed, however, that the problems cropped up in only car that they know about — the one bought by Consumer Reports — and they’ll have to wait for the results of their annual survey to see what problems (if any) have been experienced by other owners.

“Based on last year’s big auto-reliability survey,” the magazine said, “we gave the Tesla Model S a score of average, based on input from 637 owners of 2012 and 2013 models. By September, Consumer Reports will be analyzing this year’s reliability survey, which will also include the 2014 models. It will be interesting to see how the Model S will score after we tabulate the new data.

“Given the number of bits and pieces Tesla has replaced on our car, it might be tempting to guess that its reliability score will go down. The reality is, it might—depending on the frequency and severity of problems reported by our subscribers and whether they show that reliability is below average.

“Bear in mind that the experiences with our test cars are purely anecdotal and never factor into our reliability ratings. After all, it’s a sample size of one.

“Along with the rest of the motoring world, we anxiously await the conclusions of our latest reliability analysis due this fall.”
